Drug Description


Memantine is prescribed for managing cognitive impairment of moderate to severe intensity associated with Alzheimer’s disease. While it does not constitute a curative intervention for Alzheimer’s disease, it has demonstrated the potential to enhance cognitive faculties, augment awareness, and facilitate the execution of daily activities. 

The mechanism of action of this medication involves the inhibition of a specific endogenous neurotransmitter in the brain, glutamate, which is hypothesized to be intricately involved in the manifestation of Alzheimer’s disease symptoms. 

Uses and Dosage 

Take this medication orally once daily as directed by your physician. Swallow the capsules whole; do not crush or chew them to prevent potential adverse reactions. If swallowing whole is difficult, you can open the capsule and sprinkle the contents on applesauce but consume it immediately. Do not prepare this mixture in advance. 

The dosage depends on your condition and response; your doctor may start with a low dose and adjust it as needed. Follow your doctor’s instructions closely. 

If transitioning from another form of memantine to the extended-release version, consult your healthcare provider before switching. 

For optimal effectiveness, take the medication at the same time every day.
